Acrate is pulled by a force (parallel to the
incline) up a rough incline. the crate has an
initial speed shown in the figure below. the
crate is pulled a distance of 8.05 m on the
incline by a 150 n force.
the acceleration of gravity is 9.8 m/s
2
a) what is the change in kinetic energy of
the crate?
answer in units of j.
b) what is the speed of the crate after it is
pulled the 8.05 m?
answer in units of m/s.
